High Performance Spherical Ceramic Sand Factory and Suppliers in China
Ceramcast spherical ceramic sand is a high-performance refractory material specifically engineered for precision sand casting. Composed of a Mullite and Corundum mineralogical structure, this advanced ceramic sand offers an exceptional refractoriness of ≥1800℃, making it the ideal choice for high-temperature casting environments where standard silica sand fails. Its superior spherical morphology significantly enhances mold breathability and surface finish, reducing casting defects and improving overall dimensional accuracy.
Designed for versatility and sustainability, Ceramcast is compatible with a wide range of binders, including acid and alkali resins. Whether applied in 3D sand printing, cold box processes, or lost foam casting, it delivers unmatched stability and a high reclamation rate of up to 98%. By combining low thermal expansion with a bulk density similar to silica sand, Ceramcast optimizes production efficiency while drastically reducing industrial waste and procurement costs for modern foundries.
